Description
Is your feature request related to a problem? Please describe.
I know this project was just announced today, but I'd like to see #![no_std] support added, as I was looking to integrate zstd in my rust osdev project.
Describe the solution you'd like
The programs directory could be it's own crate and no_std support could be added to c2rust-lib. The dependency on the libc crate would have to made optional (as far as I can tell it's only used for size_t, malloc is already partially feature-gated).
Describe alternatives you've considered
So far I've only seen ruzstd which has limited compression levels and is probably slower. Alternatively I could use C bindings to zstd but I'd prefer a pure rust library like this one.

Research direction
Start by examining the programs directory and the c2rust-lib crate, then trace where the libc dependency and existing malloc feature gates are used. Check how the programs directory could become its own crate and determine whether libc can be optional while preserving the requested no_std support; done means the relevant crates build for no_std without requiring libc.
